   An administrator is configuring a virtual server for a web application that requires HTTP/2 support. The virtual server is assigned an HTTP profile and a TCP profile. Clients using HTTP/2 can connect, but the application is not functioning correctly. The administrator notices that the HTTP profile is configured with an 'HTTP/2' setting that is enabled. What is the most likely cause of the application failure?

   • AThe HTTP profile is configured with an incorrect 'HTTP/2' setting, such as 'Prior Knowledge', which is not supported by the client.
   • BThe TCP profile is not compatible with HTTP/2, causing the HTTP/2 frames to be dropped.
   • CThe TCP profile is configured with a 'Delayed ACK' setting that is incompatible with HTTP/2, causing the connection to be slow.
   • DThe virtual server is missing an HTTP/2 profile, which is required for HTTP/2 support.

   A virtual server has a client SSL profile that requires TLS 1.2 and a server SSL profile that only supports TLS 1.0. What is the most likely outcome for HTTPS traffic?

   • AThe BIG-IP will automatically upgrade the server SSL profile to TLS 1.2 to match the client profile.
   • BHTTPS traffic will be processed, but the backend connection may use TLS 1.0, which could cause compatibility or security issues.
   • CThe virtual server will use TLS 1.2 for both client and server connections because the client profile takes precedence.
   • DThe virtual server will reject all HTTPS traffic because the profiles are incompatible.

   A virtual server is configured with both a TCP profile that enables delayed ACKs and an HTTP profile that requires immediate ACKs for keep-alive connections. What is the most likely result of this profile combination?

   • AThe virtual server will fail to load because profiles with conflicting settings cannot be assigned together.
   • BThe HTTP profile will override the TCP profile's delayed ACK setting, and traffic will process normally.
   • CTraffic may experience performance degradation or connection issues because the conflicting ACK settings can disrupt the expected TCP behavior.
   • DThe BIG-IP system will automatically disable the TCP profile to resolve the conflict.

   A virtual server is configured with a persistence profile that uses source address affinity, but the application requires session persistence based on a cookie. What is the most likely result?

   • AThe BIG-IP will automatically switch to cookie persistence when it detects the application's requirement.
   • BThe virtual server will fail to load because the persistence profile is incompatible with the application.
   • CSessions will be persisted correctly because source address affinity is a valid persistence method.
   • DSessions may be directed to different pool members because the persistence method does not match the application's needs.
